Yes, there would be UV degradation - of the Kevlar cloth *and*
the resin.  UV radiation degrades just about every man-made
thing.  UV-absorbing additives aren't a magic bullet to prevent
UV degradation forever and ever, they just slow it down.

Not sure where you're heading with the question, but to maximize
the life of the boat it would be good to store it in the garage
or somewhere out of the sunshine.  And if you really want to be a
fanatic about it, get a boat cover made for the boat when it's
being transported.
